Hubble-Spitzer colour mosaic of the galactic centre

This composite colour infrared image of the centre of our Milky Way galaxy reveals a new population of massive stars and new details in complex structures in the hot ionised gas swirling around the central 300 light-years. This sweeping panorama is the sharpest infrared picture ever made of the Galactic core. It offers a nearby laboratory for how massive stars form and influence their environment in the often violent nuclear regions of other galaxies.
